Politics. Religion. Nabucco is Verdi's retelling of the Old Testament story of King Nebuchadnezzar II's religious conversion. On one side, the fiery Hebrew priest Zaccaria, battling to lead his people from oppression. On the other, Nabucco, the tyrannical Babylonian king and his adopted daughter Abigaille, who will stop at nothing to get her father's throne and her sister's lover. Will King Nabucco's ambition rob him of his beloved daughter as well as his kingdom?
